Product Information

Kia's confidence in the Soul extends to its warranty, too: it offers seven years. It's a reliable car to start with, particularly in its first three years, but it's nice to know that Kia has you covered well into the car's life. The Soul's position on this list is because cars like it are so vital. Petrol and diesel cars are not sustainable for our planet, but electric cars with effective ranges of less than 100 miles aren't the answer. The Soul, with its long range and efficient battery, is. Read our Kia Soul EV review.

More information on quality can be found in this old but still very helpful article from Harvard Business Review. However, a higher BTU also means a higher price tag, and likely higher running costs, so it's a balancing act of investing as much as you can for better performance against how much you're willing to pay upfront for a unit. Room size Getting the AEG unit set up was easy (except for the bit where we carried it from the street to the apartment; at 30kg it's very heavy!). Once set up, it’s a highly effective unit that’s able to effortlessly keep your average UK living or bedroom cool down to temperatures of 16˚C. In tests, we managed to cool our mid-sized living room from 24˚C to 20˚C within an hour. We also like that the unit uses a more environmentally friendly R290 refrigerant. We tried the De'Longhi Pinguino out in a hot loft bedroom and it was very effective at keeping the room cool and comfortable in a sweltering summer heatwave.

Who knew a pair of headphones could be so controversial, but when the original AirPods launched in 2016, many thought Apple had lost the plot. With no wires connecting the earpieces, the brilliantly white clubs of plastic sat in your ears and Apple told us they would stay there. Few believed it. Cue numerous stories focused solely on whether the pods would fall out. The concerned press and prospect of forking out for a single earpiece if one fell out could have spelled doom for the AirPods, but a walk in any town centre today shows truly wireless in-ear headphones have caught on. However, they can last a long time. Good quality, well-looked-after units are able to last for five to 10 years.

The unit performed solidly during our testing, reducing the temperature in the room by 2°C in 10 minutes. Like most air con units it isn't silent, there's 51-53dB of noise depending on if you opt for the low or high cooling setting, but it's a downside our testers were happy to accept in return for its temperature-reducing powers.

Most won’t cool below 16C. Remember to close doors and windows and close curtains to keep sunlight out. You get two window kits with the supplied 1.8m duct as standard – a fabric one designed to be attached via supplied Velcro strips, plus one that comprises a trio of hard plastic window ‘plates’. When joined together, the latter also allows you to vent the duct through a sliding door – though you’ll be left with a small gap at the top. This is still far better than the window kits offered with most air conditioners, a big point in the Meaco’s favour. While this Midea Comfee won't manage larger rooms, it's decent for bedrooms and home offices that overheat in the summer.There are a few differences between air conditioning units and air coolers, so it’s good to know what these are before buying, that way you can ensure you’re getting the best product for your needs.
